Sand mastic for homes and businesses in Buckland
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. If you have modern sealant on a period surround and tired mastic found when preparing windows for paint, we can help.
In a village or hamlet like Buckland, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or email us.

DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Buckland, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What you get with us
- Over 20 years’ experience
- Trusted Arbo and Everbuild sealants
- Every job guaranteed for a year
- Approved under the ARBOMaster scheme
What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a few hours per window, depending on the condition of the joints, and the area is left clean. Somewhere as small as Buckland, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- For indoor joints, keep the area dry beforehand if you can

Related advice
When to call us in Buckland
Some old mastic was never deep enough. A thin layer does not hold well, which is why we pack deep voids first and get the depth right.
Keep an eye out for these signs:
- Cracked mastic round a front door frame
- Gaps where the frame meets the masonry
- Mastic that needs renewing before redecorating
- Old cement repairs round a window that have failed
For site and facilities teams at buildings such as Buckland Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Sand mastic in Buckland: local notes
Historic houses like Longworth House (about 2.6 miles east) are a reminder that the area around Buckland has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Homes close to Roman Catholic Church of St George include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
